Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CNY17-2 is determined by strict adherence to the following criteria:

Fixed Parameters (Non-Negotiable):

• Isolation voltage: 5000Vrms
• Number of channels: 1
• Output configuration: Transistor with Base
• Package: 6-DIP (0.300", 7.62mm)
• Mounting: Through Hole
• Input type: DC
• RoHS3 compliance status

Variable Parameters (Allowable Range):

• Current Transfer Ratio (CTR): Minimum 63% @ 10mA, Maximum 125% @ 10mA
• Voltage Output (Max): 70V or higher
• Vce Saturation: 300mV or lower
• Operating temperature: -55°C minimum, 100°C or higher maximum
• Forward voltage (Vf): 1.4V to 1.65V
• DC forward current (If): 60mA or higher

All substitute parts listed below maintain the fixed parameters while operating within the allowable ranges for variable parameters.

Parameter Comparison

Engineering Selection Recommendations

CNY17-2-000E (Broadcom Limited) is the direct electrical equivalent to CNY17-2. This substitute maintains identical Current Transfer Ratio specifications (63% to 125% @ 10mA), matching performance characteristics for applications requiring this specific CTR range. Both parts are Active status with ROHS3 compliance and unlimited MSL rating. The CNY17-2-000E is packaged in Tube format and maintains all critical electrical parameters within specification.

CNY17-3-000E (Broadcom Limited) provides higher Current Transfer Ratio performance (100% to 200% @ 10mA) while maintaining all fixed parameters. This variant is suitable for applications where increased CTR provides design margin or improved switching characteristics. Active status and full compliance certifications apply.

CNY17-4-000E (Broadcom Limited) offers the highest Current Transfer Ratio range (160% to 320% @ 10mA) within the CNY17 family. This variant is appropriate for designs requiring maximum current transfer efficiency. Active status and compliance certifications are maintained.

CNY17-1-000E (Broadcom Limited) provides the lowest Current Transfer Ratio range (40% to 80% @ 10mA). This variant is suitable only for applications where lower CTR is acceptable or required. Selection of this part requires verification that the reduced CTR range does not compromise circuit performance.

All substitute parts operate within the -55°C to 100°C temperature range, which is narrower than the CNY17-2's -55°C to 110°C range. Applications requiring operation above 100°C must retain the original CNY17-2 part.

Frequently Asked Questions (FAQ)

Q: Can CNY17-2-000E directly replace CNY17-2 in existing designs?

A: Yes. CNY17-2-000E maintains identical Current Transfer Ratio specifications (63% to 125% @ 10mA), isolation voltage (5000Vrms), package configuration (6-DIP Through Hole), and all other fixed electrical parameters. Both parts are Active status with ROHS3 compliance.

Q: What is the primary difference between CNY17-1-000E, CNY17-2-000E, CNY17-3-000E, and CNY17-4-000E?

A: The primary difference is Current Transfer Ratio (CTR) performance. CNY17-1-000E provides 40-80% CTR, CNY17-2-000E provides 63-125% CTR, CNY17-3-000E provides 100-200% CTR, and CNY17-4-000E provides 160-320% CTR. All other electrical and mechanical parameters remain constant across the family.

Q: Are there temperature range limitations when substituting with Broadcom parts?

A: Yes. Broadcom CNY17 variants operate from -55°C to 100°C, while the Everlight CNY17-2 operates from -55°C to 110°C. Applications requiring operation above 100°C must use the original CNY17-2 part.

Q: Do all substitute parts maintain the same package and mounting configuration?

A: Yes. All listed substitute parts use 6-DIP (0.300", 7.62mm) Through Hole packaging, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Q: What compliance certifications apply to all parts in this comparison?

A: All parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Broadcom parts carry additional REACH Unaffected status. All parts are classified as Active products.

Q: How does output voltage rating differ between the main part and substitutes?

A: CNY17-2 specifies 80V maximum output voltage, while all Broadcom substitutes specify 70V maximum. Applications requiring output voltages above 70V must retain the original CNY17-2 part.

Q: What inventory considerations apply to these substitutes?

A: CNY17-2 has 43,100 pieces in stock. Broadcom alternatives have lower inventory: CNY17-1-000E (4,250 pcs), CNY17-2-000E (8,275 pcs), CNY17-3-000E (9,859 pcs), and CNY17-4-000E (12,550 pcs). Inventory levels should be verified at time of procurement.
